Sending email from your own domain is anything but easy. You need SPF, DKIM and DMARC at minimum. Are you going to host your own mail server? No one will accept your emails. Will you use sendgrid or postmark or SES? Enjoy having your emails (especially in the beginning) randomly end up in spam folders or worse completely quarantined (no bounce, nothing in spam folder) for various large institutions using MS Forefront.

Hold on, what? Okay, return false if they aren't equal, then open another process to repeat this method once again in the shell... I can't guess the reason. Would you know if there is any reason this might have been done?

It's true. I went from pretty good eyesight to +3.25 over a relatively short period of time, but it wasn't an option to wait any longer, I had these crazy headaches and did not realize they were caused by my eyesight being off. The initial glasses were +1.5 and made a world of a difference. 6 months later is was +2.0, another six months and it was at 3.0. That's when I got scared wondering how bad it was going to get but it actually leveled off and took another year or so to go to 3.25 and I've had these for a year now and no difference. I even bought a couple to not have to switch to different models when these wear out (which they inevitably do, they're consumables to me, not something to treat with great care, a couple of hours in the shop and they'll definitely fall at least once on a concrete floor).

Pre-Uber, either the driver rented the car to a middleman who rented the medallion from a rich owner, or said owner was selling and financing (most banks won't touch these medallions!) a medallion at a ridiculous interest rate to a driver that planned to use it as his retirement savings (an extremely volatile asset and not very liquid). The more I spoke to cab drivers the more it seemed their industry was a pyramid scheme aimed at helping established rent-seeker take advantage of often poor new immigrants.

Uber brought a breeze of fresh air: Someone could simply buy a car, calculate the depreciation and it's value on the market (since unlike medallions cars are relatively liquid assets!) do rideshare and calculate their profits or loss. They can get out of the game at anytime, and they know exactly how much they are going to get for the car they have should they sell it.
Yes, I believe it was.

Voting by hand takes days - in the US. Not in Finland, France or the many other countries where voting is done by hand 100% successfully for decades with timely results.

Here's the conundrum - what constitutes what's "out of threshold"? If a voting machine, either by design or flaw, pushes a close vote outside the threshold - then that's a way to bypass the checks & balances and can be exploited by the unethical.

Once you get the "feel" doing wattage is pretty easy on a static trainer if you change gears or your pedal stroke rate. That amount of practice and effort to learn when you only want to spend 10-20 minutes working out is beyond a beginner. Aviron's whole website is built around games and varied resistance. Having the rower do all the thinking for the user ala zwift workouts on a tacx is attractive.

I don't understand why pelotons are popular when a tacx/wahoo/etc are lightyears ahead in feel and blunting the peaks of "pain" from beginner mistakes. The more advanced ERGs that adjust are super forgiving and the same would be for rowing, avoiding pulling too much lbf and having your arms hurt for weeks = avoiding the workouts.

People doing HIIT cardio usually blow up if they put out 10% more wattage for a minute or two than their FTP. If a machine makes it so you can workout "forever" and simplifies the interface of games/workouts so users only need to focus on a single metric for game while adjusting all the others, it would be a killer feature.
Covid isn't deadly enough by a longshot. 100% of the people on this planet will die, if the entire planet got infected only 0.28% would die of covid. of the 99.72% that is not going to die of covid, 16% are going to get heart disease as cause of death.
There's an interesting paragraph in there:

"myopic defocus is already in use in the US with a contact lens, “MiSight® 1 day” by CooperVision, which is U.S. Food and Drug
Administration (FDA) approved to slow the progression of myopia. This product, which uses multifocal contact lens technology,
passively stimulates the entire peripheral retina with light myopically defocused by the non-central power of the contact lens. Kubota
Glasses technology leverages nanotechnology in its electronic glasses-based device and seeks to reduce the progression of myopia by
actively stimulating the retina for shorter periods while maintaining high-quality central vision and not affecting daily activities."

Which seems to indicate the main beneficiaries will be children, to slow the progression of myopia. As it mentions, there are already multi-focal contact lenses used for that purpose.

Since the contacts don't seem to be marketed at adults, I suspect this will be similar.

It was in their security hub which is perhaps better or worse than the thermostat depending on your view.
Based on my own experience I would not do this again. I did this for a while starting in 2001, and then for a bit from 2005-2010.

Essentially what happened a lot was that the domain providers seemed to realize that email hosting was a pain (it is, but it also isn't, depending on your time and resources), and so there were relatively frequent plan changes and service quality changes. It wasn't their core business, and this "core" thing always comes up in internal discussions when people are annoyed by something they're doing which they don't like doing.

Running my own mail server has been easier. G Suite and Fastmail have also been easier.

However I wouldn't call the domain registrar experience a bad experience. So if the numbers add up for you, why not try it?

I'd also treat the business v. personal as a separate problem. For example maybe you could get a personal email at a lower-cost domain name and own two domains, never a bad idea.
Notice the "official support" there. GPD does not officially provide any Linux distro installed on their devices (at least the GPD Win series, which is the what comes the closest to the Pyra). You have to do it all yourself - and the GPD Win 2, at launch, needed some extra patches on Linux for its specific controls (not provided by GPD, that goes without saying).
Mistrust is getting an undeserved bad rap. It is unpopular but it is an adaptation to widespread lack of trustworthiness. The lack of popularity has some motivated reasoning elements - it isn't reassuring to believe that mistrust is the right option, it isn't conceived of as "how it should be". It feels better to say "You should be able to trust the people around you." even if they really aren't. As an idea it is "uncuddley". Not all mistrust is correct nor rational of course.
Just for context, standard is defined on two fronts.

1. Each machine computes effective Watts differently, so pulling your guts out might be 1kW on one machine, and 400W on another. Whichever one everyone has the most experience with wins here.

2. There are a bunch of different designs across about three different resistance modes available A. air B. water and C. hydraulic piston. Air is generally regarded as the best as it doesn't change felt resistance with time, though it can be somewhat noisy, maybe 70dB. Water heats up as all the energy is dumped into it without anywhere else for it to go, so the viscosity changes very noticeably over a long workout. These also tend to have a nylon strap instead of a chain which stretches and can cause an odd sensation. Finally the worst, hydraulic piston, which has the smallest mass to dump energy into, will change resistance dramatically in a short time, and have been known to fail with experienced rowers, sometimes explosively.

There is room for an electrical resistance variant in this lineup, as has been shown with cycling, though it's important to note that thermodynamics specifies the energy has to go somewhere, and you may end up with a dangerously hot resistor bank somewhere on the machine.

It should also be noted that experienced rowers can output a considerable amount of power. Enough to cause piston rowers to overheat and explode/vent. Just because your resident mechanical engineer can't break the prototype doesn't mean you shouldn't find someone who can hit National Team numbers and have them go at it for an hour straight.

Ask HN: Does knowing the author of an idea help or hinder its acceptance?
So I'm curious what this community thinks about how much knowing "who" had an idea affects the progression of that idea through your organization. Is it possible to find truly great ideas when the author of it might be a "lower rank" than someone else with a mediocre idea? i.e. Your boss shares their idea with the company the same time you do. On the flip side, is the authority of the idea author a requirement to vet ideas the way knowing how much it might cost would be?

Looking forward to the discussion! :)
More details from the Bloomberg PR:

Kubota Glasses technology works to reduce the increase in axial length associated with myopia by projecting myopically-defocused virtual images generated using micro-LEDS on the peripheral visual field to actively stimulate the retina.

Viruses are believed to become less deadly over time when being less deadly offers an evolutionary advantage in ability to spread. If being more deadly and more spreadable have the same mechanism (e.g., avoiding spike protein-inhibiting antibodies), you can expect that old adage not to hold true over the short-term.
Recent Leafs have added it since, around the same time Teslas added it (but well after GM did, as GM will point to its Michigan Proving Grounds as a bitterly cold battery workout and saw active thermal management as an early requirement).
Aside from HorribleSubs, these days you can hardly throw a rock without hitting a major streaming service that offers anime.

On the surface, it sounds really nice. But anyone who’s paying attention in the fake news era has a general idea on what this will be used for.

Any tweets questioning the official narrative will be roundly criticized and ridiculed. Instead of having to delve into a long reply thread to see debunkers make their case, there will be an easy to digest notice within grasp. Which is not necessarily a bad thing if it is used fairly and responsibly. But judging on Twitter’s past performance, it likely won’t be.

Dissent will be publicly humiliated while pure disinformation from governments, think tanks, and corporations have no such objections. Any doubts to the accepted story will be pointed at one of the fact checker sites and further inquiries censored.

In an honest world, this would be one giant step to finally getting at the truth. But this isn’t an honest world, is it?
When I worked at MS Azure, we had to pay for Azure servers! (I believe our team had a $5k/month Azure bill.) It's part of internal budgeting, so that people within MS don't splurge on expensive things (because it does cost MS money for each person on Teams).
This does not address my point at all, which is that if it locks out OTHER parties that currently abuse third party cookies from tracking, there's a substantial improvement for user privacy from those parties.

Not to mention that while adblockers currently do not do anything against this practice, this does not mean that adblockers can never come up with anything to block this tracking.
There is Orthokeratology, which physically deforms the cornea via a contact lens, and lasts about a day or two. But it isn't ideal, and can have bad outcomes.

This result is the absence of bad news. No more, no less.

Regardless of what this early result is, the only thing most of us can do is try to keep social distancing, use masks, and get vaccinated to protect ourselves as best as possible.

If the vaccine doesn't actually protect us against the newer strains, we should still take it because we need protection from the more widely strain regardless. The only difference is whether we'll need to take a second vaccine in another year.
The show I watched was a recent release, but it went through Netflix jail so I guess that's why it got the high-quality fansub treatment. There weren't any official subtitles for groups like HorribleSubs to yoink day of release which bought time for a high-effort group to do their thing.
Many temptations of an open-source Chrome extension developer
Because the next law will require Google to stop omitting those sites.
"In-memory" doesn't mean so much as it once did. Faulting a page into cache from RAM takes hundreds or even thousands of cycles. Same for faulting an index page, if the whole index doesn't fit in cache.

A B-tree replaces a log2(N) binary search of the whole range into a K-ary search, with log-base-K(N) probes; but adds searches through the K keys per tree node, which all have to be brought into cache.

Even once the K keys have been brought into cache, a binary search in the index page is quite slow on modern hardware because the iterations involve randomly mispredicted branches.

A great advantage of PGM indexes seems to be that the whole index can be held in (L3) cache. Faulting a line from L3 to L1 cache takes only ~30 cycles. Once the index has been walked, you are close to the desired record and can walk forward or back a few steps to locate it.

If you have to handle insertions, it is often better to keep an overflow table searched first (or last) so you can batch-rebuild during downtime. Deletions may be handled by marking dead entries, and updates are easy. Most multigigabyte tables don't see much churn, relative to their size.
Major new sites, mostly magazine publishers, were doing this. Washington Post, TIME, Newsweek, and CNN as I recall. Five-thirt-eight according to comments here. Some may have dropped them by now, many were discussing this as negative brand value within recent years.

That's a nice sentiment in a vacuum, but we're not in a vacuum. It's sort of like focusing on getting every child a college education when you can't even manage to teach them all literacy yet.

At the point, I feel like the priority needs to be around figuring out a way to defeat disinformation and misinformation to restore some kind of common ground understanding of the facts. The marketplace of ideas can't function if major factions reject truth-seeking in favor of blatant lies that are appealing for various other reasons (e.g. emotional satisfaction, ability to manipulate others, etc.).
